Battery Replacement
The battery in the transmitter is
weak and should be changed if it
does not work at the normal range in
any location.
Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage
the transmitter.
To replace the battery, use
a flat, thin non-metal object or
tape-wrapped metal object.
1. Separate the transmitter.
2. Remove the module. 3. Open the module cover.
4. Remove the old battery.
5. Insert the new battery,
positive (+) side facing up.
Replace with a CR2025 or
equivalent battery.
6. Snap the module back together and replace it in the transmitter.
7. Snap the front and back of the transmitter together.

When the Virtual Advisor feature of
OnStar Hands-Free Calling is used,
the vehicle also sends OnStar the
vehicles GPS location so they can
provide services where it is located.
OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless the vehicle is in
a place where the wireless service
provider OnStar has hired for that
area has coverage, network capacity
and reception when the service is
needed, and technology that is
compatible with the OnStar service.
Not all services are available
everywhere, particularly in remote
or enclosed areas, or at all times.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannot
control that may prevent OnStar
from providing OnStar service at
any particular time or place. Some
examples are damage to important
parts of the vehicle in a crash, hills,
tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar buttons
is red, the system may not be
functioning properly. If the light
appears clear (no light is appearing),
your OnStar subscription has
expired and all services have been
deactivated. Press the OnStar button
to confirm that the OnStar equipment
is active.

Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel fill.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview on page 9-6
for the location of the engine oil
dipstick.
1. Turn off the engine and give the oil several minutes to drain back
into the oil pan. If this is not done,
the oil dipstick might not show the
actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.

What to Add
Use only new DOT-3 brake
fluid from a sealed container.
SeeRecommended Fluids and
Lubricants on page 10-15 .
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{CAUTION
With the wrong kind of fluid in the
brake or clutch hydraulic system,
the brakes or clutch might not
work well. This could cause a
crash. Always use the proper
brake fluid. Notice:
Using the wrong uid can
badly damage brake or clutch
hydraulic system parts.
For example, just a few drops
of mineral-based oil, such as
engine oil, in the brake or clutch
hydraulic system can damage
brake or clutch hydraulic
system parts so badly that they
will have to be replaced. Do not
let someone put in the wrong
kind of uid.
If brake uid is spilled on the
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on the vehicle. If you do,
wash it off immediately.
Battery
This vehicle has a maintenance
free battery. When it is time for a
new battery, see your dealer/retailer
for one that has the replacement
number shown on the original
battery’s label. See
Engine
Compartment Overview on
page 9-6 for battery location.
{WARNING
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California
to cause cancer and reproductive
harm. Wash hands after handling.

To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or
a manual transmission in
NEUTRAL before setting
the parking brake.
Notice: If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter. Turn off the radio
and all lamps that are not needed.
This will avoid sparks and help
save both batteries. And it could
save the radio! 4. Open the hoods and locate the
batteries. Find the positive (+)
and negative (−) terminal
locations on each vehicle.
See Engine Compartment
Overview on page 9-6 for
more information on location.
{CAUTION
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{CAUTION
Using a match near a battery
can cause battery gas to explode.
People have been hurt doing this,
and some have been blinded. Use
a flashlight if you need more light.
(Continued)
CAUTION (Continued)
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is
low, add water to take care of that
first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{CAUTION
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
